ffmpeg-v4l2-request-fourier: route remaining H.264 qpel 8x8 positions through daedalus-fourier (0012)

Closes the H.264 qpel substitution.  Extends 0007 (which routed only
mc20 put_) to ALL 15 useful positions in BOTH the put_ and avg_
tables, skipping mc00 (integer copy / pointer-only fast path).

29 substitutions total: 14 new put_ + 15 avg_.  Each wraps a single
daedalus_recipe_dispatch_h264_qpel_{avg_,}mcXY call (the dispatches
landed in daedalus-fourier PRs #15-#20).  Collapsed via a single
DEFINE_QPEL_WRAPPER macro on the libavcodec shim side so the diff
is uniform.

All recipe-table entries route AUTO to CPU NEON — no QPU shaders
for any qpel position other than mc20 yet.  Plumbing-only
NEON-to-NEON via the daedalus recipe layer; bit-exact against
the in-tree ff_*_h264_qpel8_*_neon path (each daedalus dispatch is
already bit-exact-gated by the corresponding fourier PR's test).

16x16 qpel tables ([0][...]) stay on the in-tree NEON.  daedalus
only exposes 8x8 today; 16x16 substitution can land once fourier
provides those variants.

Verified the patch applies cleanly on top of 0001-0011 against the
pinned upstream commit b57fbbe5 on hertz.
